Description

Technical Field

[0001] This invention belongs to the field of voice call technology, and in particular to a medical call method and system. Background Technology

[0002] In healthcare, real-time voice communication between patients and medical staff is a core means of enabling immediate communication about patient conditions and providing treatment guidance. This is especially crucial in emergency situations and isolation treatment, where the ability to quickly establish a stable two-way voice link directly impacts treatment efficiency and patient safety. However, current mainstream medical call systems have significant limitations in implementing voice communication functions and are no longer adequate for the needs of modern medical scenarios.

[0003] Existing systems are generally based on one-way signal transmission of "call-response" and lack native two-way voice communication capabilities. After a patient triggers a call, they can only attract the attention of medical staff through sound and light prompts. If they need to further describe their condition or receive guidance, they often have to wait for medical staff to arrive on site or rely on additional equipment such as telephones or walkie-talkies for secondary communication. This process has a significant time lag, which may delay the opportunity for treatment in emergency situations.

[0004] Even when some systems possess basic voice interaction capabilities, their implementation presents numerous inconveniences: patients may need to manually operate complex buttons to initiate a call, posing an obstacle for those with mobility impairments; others may only support one-way voice transmission, leaving patients passively receiving information and unable to provide real-time feedback on symptom changes. In special settings such as isolation wards and infectious disease areas, the lack of or inconvenience of voice communication capabilities is even more pronounced. The inability of patients and medical staff to communicate instantly via a convenient voice link increases the risk of cross-infection and reduces the efficiency of collaborative diagnosis and treatment.

[0005] With the advancement of smart healthcare systems, the demand for convenient voice call functionality is becoming increasingly urgent in remote diagnosis and treatment, multi-departmental collaboration, and other models. The shortcomings of traditional systems in areas such as the construction of two-way voice links and the ease of triggering real-time calls have become key factors restricting the improvement of medical communication efficiency, necessitating technological innovation to build a more direct and efficient voice call mechanism. This invention proposes a medical voice call method and system, which is a solution to the aforementioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a medical voice call method and system, in order to overcome the shortcomings of the prior art and provide a more convenient method and system for remote communication between patients and doctors, so that patients can receive better assistance.

[0007] To achieve the above objectives, in a first aspect, the present invention provides a medical voice call method, comprising: a device end recognizing a user's voice command, and executing a task of calling a server or configuring a network according to the user's command;

[0008] When a user issues a network configuration command, the device enters network configuration mode to configure the name, password, and IP address of the WiFi network to be connected to.

[0009] When a user issues a call command, the server-side interface displays "Answer" and "Reject" buttons. Selecting "Answer" will establish an audio call with the user.

[0010] During an audio call, the device's microphone collects audio data and transmits it to the server's speaker for playback, while the server's microphone collects audio data and transmits it to the device's speaker for playback.

[0011] Optionally, a specific voice command is required to wake up the device before sending a call to the server or configuring a network voice command to the device.

[0012] Optionally, when the user issues a network configuration command, the device enters a network configuration mode to configure the WiFi network name, password, and server IP address to be connected, including:

[0013] To switch the device from STA mode to AP mode, the user needs to connect to the device's WiFi network using a computer and enter the device's IP address in a webpage to access the device's network configuration interface.

[0014] In the network configuration interface, configure the WiFi network name, password, and IP address of the server to be connected to on the device. After saving successfully, issue a voice command to the device to indicate that the network configuration is complete, so that the device returns to STA mode.

[0015] Optionally, when a user issues a call command, the server will announce via voice that a device is calling, and the server interface will display "Answer" and "Reject" buttons. Selecting "Answer" will establish an audio call with the user. This includes: the device and the server need to be connected to the same WiFi network, and the device needs to connect to the server through the server's IP address.

[0016] Once the device and server are successfully connected, the server can receive the call command from the device, and the server interface will display the device's MAC address.

[0017] When a call command is received from the device, the server will determine the specific device based on the MAC address and then broadcast the command via voice.

[0018] When the server does not respond for an extended period of time, or refuses to make a call, or the device fails to connect to the server, the device will issue a corresponding voice announcement.

[0019] Optionally, during the audio call, the server can adjust the volume of its own speaker and the device's speaker.

[0020] The server will display the call duration and a "Hang Up" button. You can click the "Hang Up" button to end the audio call.

[0021] Optionally, the audio data transmission process includes:

[0022] The microphone on the device side converts the collected analog audio into PCM data stream via the I2S protocol and transmits it to the ESP32 microcontroller. After the ESP32 microcontroller buffers the data, it transmits the audio stream to the server via the WiFi network using the TCP protocol. The server decodes the audio and plays it through the sound card.

[0023] The server transmits the real-time collected audio data to the ESP32 microcontroller via WiFi. The ESP32 microcontroller uses an audio decoding library to decode it into PCM format, and then transmits the digital audio stream to the DAC audio amplifier via the I2S protocol, which finally drives the speaker to play the audio.

[0024] On the other hand, the present invention also provides a medical voice call system, comprising:

[0025] On the device side, there are MCU modules, power modules, audio acquisition modules, audio playback modules and voice recognition modules. The MCU module is connected to the audio input module, audio output module, power module and voice recognition module, and is used to control the operation of each module and communicate with the server. The audio acquisition module and audio playback module are used to acquire audio data and play audio data respectively. The voice recognition module is used to recognize the user's voice commands. The power module is used to supply power to each module.

[0026] The server-side component is used to respond to calls from the device and establish voice call connections with the device.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. Enables two-way voice communication, establishing a real-time voice link between patients and medical staff without relying on additional equipment. This avoids the lag of "call-response-on-site communication" or "secondary equipment transfer," facilitating communication between patients and medical staff, significantly improving the efficiency of diagnosis and treatment response in emergency situations, and reducing the risk of delays.

[0029] 2. By optimizing triggering methods such as voice command recognition, the call initiation operation is simplified, solving the problem of the difficulty in using traditional systems due to complex button presses for patients with mobility impairments or limb disabilities. This improves the convenience of calling and ensures that all types of patients can quickly initiate a call. Attached Figure Description

[0031] Figure 2 This is a structural diagram of a medical voice call system provided by the present invention. Specific implementation methods

[0032] To more clearly and completely describe the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the protection scope of the present invention.

[0033] Reference Figure 1 This is the first embodiment of the present invention, which provides a medical voice call method, including:

[0034] S1. The device recognizes user voice commands and executes tasks such as calling the server or configuring the network based on the user commands;

[0035] Specifically, before sending a call to the server or configuring a network voice command to the device, a specific voice command is required to wake up the device. After waking up the device, a call to the server or configuring a network voice command must be sent within 10 seconds; otherwise, it needs to be woken up again.

[0036] S2. When the user issues a network configuration command, the device enters the network configuration mode to configure the WiFi network name, password, and server IP address to be connected.

[0037] Specifically, the device switches from STA mode to AP mode. In AP mode, the device acts as a wireless access point, allowing other devices to connect via WiFi. Users need to connect to the device's WiFi network using a computer and enter the device's IP address in a webpage to access the device's network configuration interface.

[0038] Specifically, in the network configuration interface, you need to configure the name and password of the WiFi network that the device needs to connect to, as well as the IP address of the server that needs to be connected to. After successfully saving, you need to send a voice command to the device to indicate that the network configuration is complete, so that the device returns to STA mode. In STA mode, the device can connect to the WiFi network and connect to the server via the IP address.

[0039] S3. When a user issues a call command, the server interface will display "Answer" and "Reject" buttons. Selecting "Answer" will establish an audio call with the user.

[0040] Specifically, the device and the server need to be connected to the same WiFi network, and the device needs to connect to the server through the server's IP address;

[0041] Specifically, after the device successfully connects to the server, the server can receive the call command from the device, and the server interface will display the MAC address of the device. The MAC address is a unique hardware identifier of the ESP32 microcontroller, which can be used to distinguish different devices. The server can connect to multiple devices at the same time, but can only have an audio call with one device at a time.

[0042] Specifically, different devices are placed at different beds. When a call command is received from a device, the server will identify the specific device by its MAC address and announce the specific bed location via voice.

[0043] Specifically, when the server does not respond for a long time, or refuses the call, or the device fails to connect to the server, the device will issue a corresponding voice broadcast. Users can determine the reason why the audio call was not successfully established based on the content of the voice broadcast.

[0044] S4. During an audio call, the device's microphone collects audio data and transmits it to the server's speaker for playback, while the server's microphone collects audio data and transmits it to the device's speaker for playback.

[0045] Specifically, during the audio call, the server can adjust the volume of its own speaker and the device's speaker.

[0046] Specifically, during the audio call, the server will display the call duration and a "hang up" button. You can click the "hang up" button to end the audio call. After the call ends, the server will retain the call duration on the server interface.

[0047] Specifically, during the audio data transmission process, the microphone on the device side converts the collected analog audio into a PCM data stream via the I2S protocol and transmits it to the ESP32 microcontroller. After the ESP32 microcontroller buffers the data, it transmits the audio stream to the server via the WiFi network using the TCP protocol. The server decodes the audio and plays it through the sound card.

[0048] Specifically, during the audio data transmission process, the server transmits the real-time collected audio data to the ESP32 microcontroller via a WiFi network. The ESP32 microcontroller uses an audio decoding library to decode the data into PCM format, and then transmits the digital audio stream to the DAC audio amplifier via the I2S protocol, ultimately driving the speaker to play the audio.

[0049] Reference Figure 2This embodiment also provides a medical voice call system, including:

[0050] On the device side, there are MCU modules, power modules, audio acquisition modules, audio playback modules, and voice recognition modules. The MCU module connects to the audio input module, audio output module, power module, and voice recognition module, and is used to control the operation of each module and communicate with the server via voice. The audio acquisition module and audio playback module are used to acquire and play audio data, respectively. The voice recognition module is used to recognize the user's voice commands. The power module is used to supply power to each module. The MCU module uses an ESP32 as the main control chip, the audio input module is an ICS43434 digital microphone module, the audio playback module is a MAX98357A module, and the voice recognition module is a SU-03T module.

[0051] The server-side component is used to respond to calls from the device and establish voice call connections with the device.

[0052] It should be emphasized that the above embodiments only demonstrate some technical implementation paths and are not intended to limit this creation. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this creation, and any technical achievements obtained without creative labor, shall fall within the scope of protection of this patent.
